05 · Why Matcha

What the bowl
does for you.

Ceremonial-grade matcha is the whole leaf, powdered, nothing discarded, nothing diluted. Every benefit below peaks in Gokujō: 30-plus days of Tana shading forces the Samidori cultivar to concentrate chlorophyll and L-theanine before first harvest. The source determines the depth.

01

Calm focus, no crash

L-theanine and natural caffeine in shade-grown Uji matcha work together for sustained, alert relaxation. Caffeine drives attention. L-theanine takes the edge off the caffeine response. Drinkers commonly report smooth energy without jitteriness or a hard crash.[1]

02

Antioxidant density

EGCG is delivered at significantly higher concentrations than brewed tea because you consume the entire leaf — nothing steeped and discarded. Associated with reduced oxidative stress and long-term cellular health.[2]

EGCG · Catechins
03

Metabolic support

Green tea catechins have been associated with improved fat oxidation in multiple studies, with EGCG shown to increase fat oxidation by up to 17% in controlled trials.[3]

Gut & liver health

Dietary fiber feeds beneficial gut bacteria. Chlorophyll — maximally intact in Tezumi first-flush leaves — is associated in research with supporting liver health and reducing hepatic inflammation.[4]

Mood & cortisol

L-theanine is associated in studies with increased alpha brainwave activity. In a double-blind, placebo-controlled trial, L-theanine significantly reduced salivary cortisol and subjective stress response.[5]

Vitamins & minerals

A single serving contributes Vitamin C, Vitamin A, Vitamin K, potassium, and magnesium — Vitamin A found in matcha but not in most brewed green teas.[6]

Quality determines benefit. The Samidori cultivar, Tana tunnel shading, and Ichibancha harvest are the conditions that produce measurably higher L-theanine, EGCG, and chlorophyll. Mass-market products use later crops and high-heat processing, which degrade all the compounds above.
